What does the +1.0mm sizing mean for these bearings?

The +1.0mm sizing indicates that these bearings are designed for use when the crankshaft journals have been machined down by 1.0mm. This is a common practice during engine rebuilds to address wear or imperfections on the crankshaft surface.

What is the construction of these main bearings?

These main bearings are built with a bimetal construction that utilizes an aluminum base. This type of material is chosen for its ability to handle engine loads and temperatures effectively.

Are these bearings sold individually or as a set?

This product is a main bearing set, meaning it includes all the necessary main bearings required to support the crankshaft in the specified Isuzu engines.

Product Details

King Engine Bearings is well-known for making solid engine components. This main bearing set is built for Isuzu 4XE1, 4XF1, and 4XC1T engines, and it's specifically sized at +1.0mm. If you're rebuilding the bottom end of your engine, these bearings are a critical part of ensuring proper oil clearance and smooth rotation of your crankshaft.

These bearings use a bimetal construction with an aluminum base, which is a common and reliable material for main bearings. This design helps manage heat and wear effectively within the engine. Because they are a +1.0mm size, they are intended for use when the crankshaft journals have been machined down by 1.0mm during an engine rebuild to clean up any imperfections or wear.
